Understanding Blood Vessel Anatomy and Functions Quiz

1. Blood from the left subclavian artery flows into what vessel as it moves towards the left arm?

Left jugular vein

Pulmonary artery

Left axillary artery

Right femoral artery

Blood from the left subclavian artery travels towards the left arm through the left axillary artery, not into the left jugular vein, right femoral artery, or pulmonary artery.

Explanation

Blood from the left subclavian artery travels towards the left arm through the left axillary artery, not into the left jugular vein, right femoral artery, or pulmonary artery.

2. Blood in the radial artery comes from what blood vessel?

Brachial artery

Popliteal artery

Carotid artery

Femoral artery

The radial artery receives blood supply from the brachial artery as it branches off into the radial and ulnar arteries in the forearm.

Explanation

The radial artery receives blood supply from the brachial artery as it branches off into the radial and ulnar arteries in the forearm.

3. Why are the pulmonary arteries and umbilical arteries called arteries?

They are connected to the lungs

They go away from the heart

They are found near the abdomen

They carry deoxygenated blood

Arteries are blood vessels that carry blood away from the heart, regardless of the oxygenation status of the blood or the specific organs they travel to. Pulmonary and umbilical arteries are named based on their direction of blood flow.

Explanation

Arteries are blood vessels that carry blood away from the heart, regardless of the oxygenation status of the blood or the specific organs they travel to. Pulmonary and umbilical arteries are named based on their direction of blood flow.

4. What is the name of the outermost layer of blood vessel?

Tunica externa (adventia)

Tunica intima

Tunica media

Tunica interna (intima)

Blood vessels are composed of three main layers - tunica intima, tunica media, and tunica externa (adventitia). The outermost layer is known as the tunica externa or adventitia.

Explanation

Blood vessels are composed of three main layers - tunica intima, tunica media, and tunica externa (adventitia). The outermost layer is known as the tunica externa or adventitia.

5. Which type of blood vessels have valves?

Veins

Capillaries

Arteries

Venules

Veins are the only blood vessels that have valves to prevent backflow of blood.

Explanation

Veins are the only blood vessels that have valves to prevent backflow of blood.

6. Blood from the common carotid artery next travels to what two blood vessels?

Internal and external carotid artery

Brachiocephalic artery and subclavian artery

Femoral artery and popliteal artery

Pulmonary artery and aorta

The common carotid artery bifurcates into the internal and external carotid artery, which are the next blood vessels it travels to.

Explanation

The common carotid artery bifurcates into the internal and external carotid artery, which are the next blood vessels it travels to.

7. Where does blood in the right subclavian artery come from?

Carotid artery

Aorta

Brachiocephalic

Pulmonary artery

The right subclavian artery receives blood from the brachiocephalic artery, which is a major branch of the aortic arch.

Explanation

The right subclavian artery receives blood from the brachiocephalic artery, which is a major branch of the aortic arch.

8. The internal carotid artery takes blood to what organ?

The stomach

The kidneys

The brain

The liver

The internal carotid artery delivers oxygen-rich blood to the brain, not to the stomach, liver, or kidneys.

Explanation

The internal carotid artery delivers oxygen-rich blood to the brain, not to the stomach, liver, or kidneys.

9. From which vessel does the descending aorta receive blood?

Aortic arch

Pulmonary artery

Superior vena cava

Coronary sinus

The descending aorta primarily receives oxygen-rich blood from the aortic arch, which is the curved portion of the aorta after it ascends from the heart. Incorrect options include the superior vena cava, which carries deoxygenated blood from the upper body to the heart, the pulmonary artery that carries deoxygenated blood from the heart to the lungs, and the coronary sinus that collects deoxygenated blood from the heart's veins.

Explanation

The descending aorta primarily receives oxygen-rich blood from the aortic arch, which is the curved portion of the aorta after it ascends from the heart. Incorrect options include the superior vena cava, which carries deoxygenated blood from the upper body to the heart, the pulmonary artery that carries deoxygenated blood from the heart to the lungs, and the coronary sinus that collects deoxygenated blood from the heart's veins.

10. Blood in the right common carotid artery receives blood from what vessel?

Vertebral artery

Internal carotid artery

Brachiocephalic artery

Subclavian artery

The brachiocephalic artery is the main vessel that gives off the right common carotid artery, supplying blood to the head and neck region. The other options either do not directly supply blood to the right common carotid artery or are not in the correct anatomical position to serve this function.

Explanation

The brachiocephalic artery is the main vessel that gives off the right common carotid artery, supplying blood to the head and neck region. The other options either do not directly supply blood to the right common carotid artery or are not in the correct anatomical position to serve this function.

11. Name the three blood vessels that exit from the aortic arch.

Brachiocephalic, left common carotid artery, left subclavian artery

Innominate artery, right common carotid artery, right subclavian artery

Superior mesenteric artery, inferior mesenteric artery, celiac artery

Left pulmonary artery, right pulmonary artery, aortic valve

The correct answer includes the brachiocephalic artery, left common carotid artery, and left subclavian artery, all of which are major arteries that branch off from the aortic arch. The incorrect answers consist of various arteries, veins, and valves that do not exit directly from the aortic arch.

Explanation

The correct answer includes the brachiocephalic artery, left common carotid artery, and left subclavian artery, all of which are major arteries that branch off from the aortic arch. The incorrect answers consist of various arteries, veins, and valves that do not exit directly from the aortic arch.
